Pacmoshing, also known as pacmanning is when at a concert, you stretch your arms out to make the shape of pacmans mouth, with your hands made into fists, you hit your fists together whilst shouting OM NOM NOM and go through the crowd 'eating' people like this.

Created by Kirsten Hobson, who planned to do it at a Megadeth + Testament concert on the 18th February 2009, with friends Benjamin Brown, Daniel Brown and Bethany O'Brien.
